The "warm" sound on the other hand is usually the result of harmonic distortion and/or compression. It's also worth noting that the vast majority of vinyl recordings made in the past 30 years have gone through a digital stage. Quote:

Bits per sample is what determines dynamic range. CDDA uses 16 bits/sample, and that gives a dynamic range of 96dB. Vinyl records have a varying dynamic range depending on several factors, but it's usually between 60-80dB (equivalent to about 10-12 bits/sample). Samples per second (or sample rate) determines the maximum frequency of the recreated signal (half the sample rate, according to the Nyquist theorem). CDDA uses a sampling rate of 44100Hz, and that gives a maximum frequency of 22050Hz. Vinyl doesn't have a real frequency limit, but is usually cut off around 20000Hz (by a brick-wall filter). Both to prevent high-frequency noise from being audible and because of the engraving process. So how are 16bits and 44.1kHz not enough? No members have liked this post.

Re: Vinyl records vs. Cds.
When the bit depth is increased is also means that those waveforms are more smoothly shaped, they more closely match the sine wave shape. This is because there are more available voltage values within the given range. Analog has an infinite number of possible voltage values within a given range. So even though vinyl may not have a great dynamic range, the sound is more accurate within that range.
Great vinyl sounds 'alive' to me, whereas CDs, even though they still often sound great, are lacking. No members have liked this post.

That doesn't mean that lesser bit depths are less accurate in general, just that they are accurate in a lesser range. Higher bit depths are often used in recording to keep noise added in the various steps from entering the final product. Quote:

And I'm not sure what you mean by accurate. The CD-system can accurately store and recreate any signal that is within the limits of the specifications of the system. A CD is a (downsampled) digital copy of the digital master. There is no way to create a vinyl record with that kind of accuracy, if that was what you meant by accurate. Quote:
But it is never going to give you the accurate and precise reproduction the digital formats are capable of. And that may be a good thing since it would probably lose its special sound if it did. No members have liked this post.

Re: Vinyl records vs. Cds.
I understand, exactly, the arguments regarding dynamic range capabilities with more bits in a sample (and that's a great post).. but here's the $64,000 question:
If these shit-head mastering 'engineers' insist on crushing the life (and nearly all dynamics) out of a recording BEFORE makeing the glass masters, what difference will it make? If the entire fucking recording only has 1 db of dynamic range, none of that shit matters. I wish someone would concentrate on getting the record companies to demand some minimum-acceptable dynamic range to be enforced by the pressing plants. They have to WANT to do it.. however that may be accomplished.

Re: Vinyl records vs. Cds.
But I want my record to be as loud or louder than so and so's on my shitty iPod earbuds!!

How much dynamic range do you think is needed? A study published by AES[1] claims 75dB is required for loudspeaker systems and 80dB for headphones. Quote:

All of my SACD classicals surpase their vinyl counterparts. I haven't heard an Impulse SACD recording that sounded inferior to vinyl. Tech. is there, but consumer support isn't. No members have liked this post.
